An object with a mass of #2 kg#, temperature of #4 ^oC#, and a specific heat of #19 J/(kg*K)# is dropped into a container with #24 L # of water at #0^oC #. Does the water evaporate? If not, by how much does the water's temperature change?
1 Answer
The water does not evaporate and the change in temperature is
Explanation:
The heat is transferred from the hot object to the cold water.
Let
For the cold water,
For the object
The specific heat of water is
The specific heat of the object is
The mass of the object is
The mass of the water is
As
You would expect this result, as the object is not very hot and the mass of the object and its specfic heat are small compared to the mass of water and the specific heat of water.
